IMPROVEMENT m COMBINED HARROW AND ROLLER.

The Schedule referred to in these Letters Patent and making part of thesame To all whom it may concern Be it known that -I, J 011x M.BLANKENBEKER, of Powers Station, in the county of Jay and State ofIndiana, have invented a new and useful Improvement in Combined Harrowand Roller; and I do hereby declare that the following is a full, clear,and exact description thereof, whiclrwill enable others skilled in. theart to make and use the same, reference being bad to the accompanyingdrawing forming part of this specification, inwhich- I v Figure 1 is atop view of my improved harrow and roller, part of the seat beingbrokcnraway'to show the construction.

Figure 2 is a side view of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved harrow, whichshall be so constructed that the ground may be' harrowed and rolled, orharrowed, rolled, and cultivated, as may be desired, and which shall, atthe same time, be simple in construction and easily adjusted andoperated; and

It consists in the construction and combination of various parts of themachine, as hereinafter more fully described.

A is the tongue, the rear end of which is hinged to the forward endoft-he short bar B, which passes through a clcvis, d, attached to theforward end of the draw-bar I).

The rear end of the short bar B has a hook formed upon it, whichhooks-into a hole formed inthe forward edge of the plate 0, which ispivoted to the forward partof the drawbar 1), by a bolt, as shown infigs. 1 and 2. I

E are the side bars of the forward part of the harrow-framc, the forwardends of which are pivoted to theforward part of the draw-bar D, by abolt, or by the upper end otthe forward tooth. 'lo/the liars E, atsuitable distances apart, are secured .the barrow-teeth F, .Which aremade broad and thin, or-paddle-shaped, as shown in fig. 2, and aresecured to the bars E with their longest diameters par-' allel with theline of draft.

The rear parts of the side bars E are adjustably connected to each otherby the cross-bars G, the ontl'ir ends of which are pivoted to the rearparts of the side bar s E, and the inner ends of which overlap eachother, pass through a slot or keeper formed in or attached to the rearend of the draw-bar D, where they are adjustahly securedin place byabolt which passes through a hole in the said rear end of the saiddraw-bar D, and through one or the other of the holes through the in-'ner ends of the cross-bars'G. By this construction the frame of theharrow may be spread or contracted, v as desired.

Upon the rear ends of the side-bars E are formed eyes, into which arehooked hooks formed upon the forward ends of the side-bars H of the rearpart of the lnn'row-fi-ame. The rear ends of the bars H are secured toeach other by a bolt, as shown in figs. 1 and 2. A

To the bars H, at suitable distances apart, are secured the teeth I,which are made a little narrower and more pointed than the teeth F, andare secured to the.bars H with their longest diameters at rightangleswith the line of draft, so as to act as cultivatort-ecth when required.

J are wheels, which are pivoted to the ends of thedownweirdly-projecting arms 16 of the crank-shaft K,- which works inbearings attached to the bars E, and upon oneend of which is formed acrank-arm, k.

L is the forward or main roller, which may be made in one or more parts,and the ends of the shaft of which are attached to thedownwardly-projecting arms m of. the shaft M, which works in bearingsattached to the rear parts of the bars E, and towhich is rigidlyattached, or upon it is formed, an upwardly-projecting arm, m

N' is the rear roller, the ends of the shaft of which are attached tothe ends of the downwardly-prtjecting arms 0, attached to the shaft 0,the journals of which work in bearings attached to the rear parts of thebars H, and toone of its ends is attached, or upon it is formed, acrank, 0

P is a crank-shaft, which works in bearings in the upper ends ofstandards attached to a plate,d bolted to the draft-bar of the barrow,and to one end ot' which shaft is attached, or upon it is formed, acrank, 1).

Q is a crank-shaft working in bearings attached to the draft-bar D, andwith which is rigidly connected the lower end of the lever R,.whichpasses through a slot in the foot-board S of the seat '1, where it isheld in place, when adjusted, by being forced into and held in one orthe other of the notches formed in the side of the said slot by thespring U.

Upon one end of the shaft Q is formed, or to it is attached, a crank, g,which is connected with the cranks a" and p, by the connecting-bar V. I

The crank 11 is connected with the crank in? by the connecting-bar VV,and with the crank 0 by the connecting-bar X, so that, by operating thelever R, the wheels and rollers may be lowered to regulate the depth atwhich the teeth work in the ground, or to raise said teeth entirely awayfrom the ground when passing from place to place.

Y is a lever, the lower end of which is pivoted to the crank 11, andwith the middle part of which is adjustably connected the forward end ofthe jointed connecting-bar Z, the rear end of which is secured to therear ends of the side bars H by the same bolt that secures said barstoeach other, so that the driver, by I means of the lever Y, can raise therear part of the harrow away from the ground, for convenience intnrning, 0r when he does not desire to cultivate the ground, but only toharrow and roll it.

This construction also enables the rear part of the harrow to bedetached from the forward part when desired. The rollers may also bedetached when desired.

Having thus described my invention,

\Vhat. I claim as new, and desire to secure by Letters Patent, is-- Thearrangement, in a combined harrow and reller, of side bars E, teeth F,adjustable cross-bar G, side bars H, teeth I, roller L, armed shaft M,roller N, armed shaft 0, wheels J, armed shaft; K, lever B, crank-shaftsQ, g P 12', connecting-bars V \V X, lever Y, and bar Z, operating, asdescribed.
